Description Said Abou-Hallawa 2022-07-08 01:07:12 PDT 
WebProcess::initializeWebProcess() sets a low memory pressure handler. This handler loops through the WebPages and call WebPage::releaseMemory() for every one. This function just calls RemoteResourceCacheProxy::releaseMemory() but this function does not release the cached shared NativeImages.
